Questions about BBTS Preorders and POL

I have several items preordered from BBTS that are supposed be available in November. My understanding from the BBTS FAQ page is that since I have the POL feature turned on, I have to "release" my items (by clicking a Release button?) when they are in stock. 4 questions:
1) Will they alert me when the items are in stock and remind me I need to "release" them, or do I have to keep logging in and checking their status?
2) Is there a "Pile of Loot" page, or do you look at your POL by just looking at your Preorders?
3) I don't see any "Release" button on my Preorders page. Will it automatically appear when the item(s) are in stock?
4) If several items become available and I "release" them, will they automatically be combined into one shipment, and if so, will my shipping charges be reduced?
